Professor Zhao Fengxue did not live on the campus of Beijing Normal University, Zhou Chen and Yang Xi walked a distance, bought some fruits at a nearby fruit store, and then walked towards Professor Zhao Fengxue's residence with a little in one hand. Pen & Fun & Pavilion www.biquge.info

According to the address provided by Director Huang, the two came to a community.

It is a slightly old neighborhood on the outside, with red bricks and green tiles on both sides of the road, and residential buildings submerged in tall locust trees and green ivy entwined with green. Soon after entering the community, you can see a sign prohibiting traffic, and at this time, the cobblestone paths stretch around the buildings, and the fragrance wafts from the shade of the green trees.

"Professor Zhao lives in Room 302 of Building 5, which should be this building."

Zhou Chen looked at the building sign in front of him, then climbed the stairs, and knocked on the door painted with green paint.

After a while, the door opened, and an old man with gray hair looked at the strange man and woman standing at the door with some strange eyes, "Who are you looking for?" He asked in surprise.

"Professor Zhao, we're here for you." Zhou Chen recognized the old man in front of him as the famous Professor Zhao Fengxue, he introduced himself with a warm smile on his face: "My name is Zhou Chen, and I am a graduate student under Professor Yang Hexin of UCAS, and we are here to visit you this time. ”

"It turns out that you are Zhou Chen! Look at me, please come in, please come in! ”

Professor Zhao reacted and looked very enthusiastic, seeing Zhou Chen and Yang Xi carrying fruits, he hurriedly beckoned the two of them to come into the house and sit.

Professor Zhao is in his early seventies this year, and it was already time to retire according to his age, but Zhou Chen found that Professor Zhao was still in good spirits, and the whole person exuded a restrained energy, and it would not be a problem to rehire him for a few more years.

Beijing Normal University also seems to have taken into account Professor Zhao's advanced age, so in addition to bringing a group of doctoral students, he is basically no longer required to give lectures to students.

Entering the room, Zhou Chen's eyes glanced slightly, and found that the layout of Professor Zhao's house was very simple, and even a little retro, some like a house in the eighties and nineties, especially the vertical shaking head fan in the living room. But in contrast to the heat outside the room, there is a natural shade in the living room, as if the sun is blocked.

"Come, Xiao Chen, sit here!" Professor Zhao happily guided Zhou Chen to sit on the sofa, and then enthusiastically poured tea for them, "Hehe, my wife went out for a walk, and I will pour this tea for you......"

"Professor Zhao, you're polite."

"Hey, sit down, don't be so restrained!"

Professor Zhao said jokingly, this is his character, he treats people very relaxed and happy, when he saw Yang Xi next to Zhou Chen, Professor Zhao hesitated slightly, he had some impressions of this girl, but he didn't seem to remember where he had seen her.

"Professor Zhao, my name is Yang Xi, and I am a third-year student in the School of Life Sciences." Yang Xi said respectfully and politely.

Professor Zhao suddenly realized, nodded and said, "Oh, I have an impression of you, when you started a big class last semester, you and another tall girl came to audit, and you and that girl asked several questions in a row. Saying that, Professor Zhao looked at Zhou Chen: "You two ......"

Zhou Chen smiled and replied, "Xi'er is my girlfriend." ”

"What a coincidence!" Professor Zhao smiled and nodded, looked at the two of them, and then smiled with relief: "Not bad, good looking, you two are really a good match." ”

Zhou Chen smiled, but when he saw Yang Xi's eyes flushing slightly, he couldn't help but grab her hand hard.

After joking the two, Professor Zhao restrained his joking thoughts, and said to Zhou Chen seriously: "Xiao Chen, you were recommended by Old Man Liang and Old Man Yang, let me tell you the truth, originally I was only going to take one doctoral student this year, after all, people are old and have limited energy, and it seems a little powerless to bring two doctoral students, but Old Man Liang and Old Man Yang patted their chests to recommend you, to be honest, I was really curious about you at that time, and I wanted to see what kind of ability you have!" ”

"I read your paper on black holes, and it is indeed brilliantly written, and I can see that your basic skills are very solid, and you also have a good talent in mathematics."

Professor Zhao looked at Zhou Chen, saw him listening carefully, couldn't help but change his words, and said with a smile: "However, only the Department of Astronomy here in Beijing Normal University has a doctoral program in astrophysics, and when it comes to my old Zhao, there is only gravity and relativity, so in order to find out how well you master the theory of relativity, I specially gave you the question of 'simultaneous transitivity'." ”

"I didn't expect Old Man Yang to rush to you after getting the question from me......" Speaking of this, Professor Zhao couldn't help laughing.

It was also the first time that Zhou Chen had heard that there was such a story before Mentor Yang Hexin came to him, and he couldn't help but feel sorry for a while.

"But what I didn't expect was that just a few days later, you sent me back an article about 'simultaneous transitivity,' which surprised me very much." Professor Zhao showed a smile on his face, and he seemed to be in a very good mood.

It is no wonder that he is so happy, on the research road of theoretical physics, it is not easy to find a good seedling, and the discovery of a superb green and has passed the withering stage of the young plant, it is even more commendable, which indicates that the young plant only needs to absorb a little more nutrients, can thrive.

"Although your article did not go beyond the framework set by your predecessors, it is still deeply cultivated in the established circle, but the level of deep cultivation is already quite hot."

Professor Zhao did not hesitate to praise him, and took the article sent by Zhou Chen as he spoke.

Putting on reading glasses and flipping the article to the place where the Lorentz transform and the inverse transformation, Professor Zhao lightly touched it and said with a smile: "Xiao Chen, you can help me explain why the formulas here have become so complicated, although it still retains a certain amount of the original form of Lorentz transformation and inverse transformation, but in fact, these groups of formulas can no longer participate in the calculation." ”

"They've become so complex that they're only suitable for mathematical."

Zhou Chen nodded, and said thoughtfully: "The Lorentz transform is the most basic relation in the special theory of relativity, and the simple Lorentz transform is suitable for the calculation of the theory of relativity, but I think mathematics is the least deceiving science, although the Lorentz transform I deduced is more complex and not conducive to calculation, it is self-consistent and correct." ”

Seeing Professor Zhao's thoughtful expression, Zhou Chen continued: "Now there is a strange phenomenon in the scientific community, that is, while maintaining the theory of relativity, all physical theories and law theorems that contradict the theory of relativity have been changed, for example, insisting that the 'equality of all inertial frames' in the theory of relativity is correct, and other theories and theorems are approximations under the theory of relativity. This is actually a bit of a deification of the theory of relativity. ”

"Well, you go on......" Professor Zhao said gesturely.

Zhou Chen nodded and said: "We should know that in the history of the emergence of the Lorentz transform and the theory of relativity, there have been two contradictory Lorentz transformations, which are the first and second meanings of the Lorentz transformation, and the theory of relativity has also appeared in the special theory of relativity and the general theory of relativity. ”

Professor Zhao thought about it carefully, nodded and said, "That's right, according to the chronological order, there should be the first meaning of the Lorentz transformation, then the second meaning, then the special relativity, and finally the general relativity." ”

Zhou Chen said at this time: "When Einstein proposed the special theory of relativity, he claimed that the special theory of relativity contains the first and second meanings of the Lorentz transformation, but in fact, the special theory of relativity with 'equality of all inertial systems' as the core is essentially the second meaning of the Lorentz transformation, which does not include the first meaning, and even contradicts the first intention in theory, but this contradiction is very vague. ”

"When the world was pursuing the special theory of relativity, Einstein himself knew that the assertion that 'the special theory of relativity is full of first and second meanings' was problematic, in fact, it was only full of the second meaning of the Lorentz transformation, and could not deduce the first meaning, so after ten years of thinking, he proposed an improved version of the general theory of relativity, and formally developed and proved the first meaning of the Lorentz transformation."

But here another problem arises, the first and second intentions are mathematically separated to prove or operate correctly, but once they are united, they are a natural mathematical contradiction! This is a very stealthy mistake! ”

Professor Zhao somewhat understood what Zhou Chen meant, and his brows tightened: "To admit the general theory of relativity with the Lorentz transformation of the first meaning as the core, it is necessary to deny the special relativity theory based on the Lorentz transformation of the second meaning, and vice versa, the two cannot be correct at the same time, or will be used!" ”

Zhou Chen nodded: "But after all, the general theory of relativity is the inheritance and development of the special theory of relativity, which absorbs part of the content of the Lorentz transformation of the second meaning that contradicts itself (the first meaning), and the result is ......."

Professor Zhao's eyes lit up, and he was surprised: "The result is...... The special theory of relativity is completely wrong because it insists on the second meaning, while the general theory of relativity is barely positive because it focuses on the first meaning, but it inherits the error of the second meaning in its bones, so it can only be said to be barely correct......"

Professor Zhao's eyes when he looked at Zhou Chen suddenly became full of amazement, "Then you look so complicated that it is almost impossible to use the Lorentz transform and inverse transformation for practical operations...... Is it a correct version of general relativity from a purely mathematical point of view? ”

"I don't know." Zhou Chen shook his head helplessly.

"From the point of view of mathematical derivation alone, this conclusion should be certain, because the derivation process is completely meticulous and self-consistent, but the mathematical formula that cannot be used for specific calculations is not as practical as the original formula that is wrong but has only a small part of the error."

Professor Zhao couldn't help but sigh when he heard this, then he shook his head and said with a smile: "It is very likely that something that lacks mathematical beauty is dross, but you are very good, and it can be seen from this incident that you have a heart that is not easy to be disturbed by the outside world." Unlike us, who deal with the theory of relativity all day long, it is easy to be blinded. ”
